Abstract

Package of a food product comprising a container and a sealing foil connected to the mouth edge of the container and a tool for picking the product, fixed to the surface of the sealing foil, wherein the sealing foil has a surface of thermoplastic plastic material, the tool is a flattened body of cellulosic or wood-cellulosic material, shaped like a spatula, and is fixed to said surface of the sealing foil by ultrasound welding, in the absence of an added adhesive material, along a section of a creasing line generated on the surface of the tool by the sonotrode during the welding process.

First claim

The invention claimed is:

1. A package of a food product comprising a container ( 2 ) and a sealing foil ( 6 ) connected to the mouth edge of the container and a scooping tool ( 16 ) for picking up the product, fixed to the surface of the sealing foil, characterized in that:
the sealing foil ( 6 ) has a plastic surface,
the scooping tool ( 16 ) has a flattened body of cellulosic or wood-cellulosic material and is fixed to said surface of the sealing foil by ultrasound welding, in the absence of an added adhesive material.

2. The package according to claim 1 , characterized in that said scooping tool ( 16 ) is fixed to the outer surface of the sealing foil along at least a section of a continuous or broken creasing line ( 40 ) generated on the surface of the scooping tool facing towards said foil, during the welding process.

3. The package according to claim 2 , characterized in that said creasing line ( 40 ) extends longitudinally from one end of the flattened body of the scooping tool to the other.

4. The package according to claim 1 , characterized in that said scooping tool is a blank of cardboard, obtained from a sheet of coupled cardboard comprising a first ( 22 ) and a second ( 24 ) layer of cardboard connected one to the other by means of an adhesive.

5. The package according to claim 4 , characterized in that said first and second layers each have a weight from 200 to 450 g/m 2 .

6. The package according to claim 4 , characterized in that said first layer ( 22 ), intended to face the sealing foil, has a basis weight from 350 to 400 g/m 2 and said second layer has a basis weight from 200 to 300 g/m 2 , the weight of said first layer being greater than the weight of the second layer.

7. The package according to claim 4 wherein said scooping tool has a continuous or broken creasing line at its longitudinal axis, said creasing line being in the shape of a groove with a depth not exceeding the thickness of said first layer ( 22 ).

8. The package according to claim 1 , characterized in that said sealing foil ( 6 ) has a laminated structure comprising, on the side facing the scooping tool, at least one thermoplastic olefinic polymer or copolymer film.

9. The package according to claim 8 , wherein the at least one thermoplastic olefinic polymer or copolymer film on the side facing the scooping tool is comprised of polypropylene.

10. The package according to claim 8 , wherein the at least one thermoplastic olefinic polymer or copolymer film on the side facing the scooping tool is comprised of bi-oriented polypropylene.

11. The package according to claim 8 , characterized in that said sealing foil further comprises one or more intermediate films of polyester or polypropylene, and a surface film of cast polypropylene, facing the container.

12. The package according to claim 11 , characterized in that the one or more intermediate films of polyester or polypropylene of said sealing foil is metallized.

13. A method for the production of a package according to claim 1 , characterized in that it comprises the operation of welding said scooping tool ( 16 ) to the sealing foil ( 6 ) by means of ultrasound welding.

14. The method according to claim 13 , characterized in that the ultrasound welding operation is carried out by generating, simultaneously with the welding, in the body of the scooping tool, a continuous or broken creasing line which extends longitudinally along at least a section of the longitudinal extension of the scooping tool and along which the tool is connected to the sealing foil.

15. The method according to claim 14 , characterized in that the welding operation is carried out by arranging a sheet intended to form the sealing foil superimposed on the scooping tool, said sheet having a surface facing the scooping tool formed by a film of thermoplastic material, and wherein the ultrasound welding operation is carried out with the use of a sonotrode ( 30 ), the active surface whereof includes a rib ( 38 ) with a V-section which is capable of generating, following compression exerted on the sheet superimposed on the scooping tool, said creasing line ( 40 ) in the tool body.

16. The method according to claim 13 , characterized in that the ultrasound welding operation is carried out with a frequency of 15 to 30 kHz.

17. A scooping tool formed by a blank of cardboard, obtained from a sheet of coupled cardboard comprising at least a first ( 22 ) and a second ( 24 ) layer, glued together by means of an adhesive and having a creasing line which extends from an end to the other of the blank, at its longitudinal axis, wherein said creasing line is a groove having a depth not exceeding the thickness of said first layer ( 22 ).
